Thanks for your reply, may I know the reason for why iphone would compatible to such Type1 or Venus Concise? Any specific reason perhaps? Or just merely the map design for such iphone device size alike?

Thanks alot

If you download and unzip each official Type* file you will find that there are only three kinds of detailed maps. If you further examine their contents by GMaptool you will find that all have the same map data except QSI data. Type1 has no QSI data, so has the minimal size and will work in all models after unlocking. If your iPhone StreetPilot supports QSI, JCV and other features then you can consider other Type* but you have to try each one by one as these maps are not announced and supported by Garmin China for iPhones.

The Venus Concise version is simply a shift-corrected Type1 detailed map.

Yes, Garmin for Iphone supports JCV and SID, I am not too sure aboust QSI as I don't really know what it means, perhaps you care to briefly explain what it does. As I said, my Iphone Garmin supports JCV, and SID. Is it means that I could try the other maps beside Type1 and Venus concised now?
